Abstract

The invention provides a battery connecting device and a battery, relates to the technical field of new energy vehicles, and is used for solving the technical problems of high foil consumption and lowutilization rate caused by the existing tab and pole connecting mode. The device comprises a body and a first connecting part connected with the body, wherein the body is connected with a pole, and the first connecting part is connected with a tab in an inserted manner; the first connecting part extends along a first direction and protrudes out of the body along a second direction, and an included angle is formed between the first direction and the second direction, so that when the battery connecting device is connected with the tab, the tab extends to the outer side of the roll core along the second direction. According to the battery connecting device provided by the embodiment of the invention, the foil consumption can be reduced, and the foil utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery connection device and a battery. Background technique [0002] Batteries are commonly used energy storage components, widely used in life, manufacturing and other fields, especially in the field of new energy vehicles. [0003] The battery includes a winding core, a casing and a cover plate. The winding core and the winding core are arranged in the casing, and the positive pole and the negative pole are arranged on the cover plate; The positive plates all have positive tabs, and each positive tab is connected to form a positive tab and is connected to the positive post. Each negative plate has a negative tab, and each negative tab is connected to form a negative tab and is connected to the negative post. When assembling the battery, in order to reduce the distance between the cover plate and the winding core, the positive and negative tabs are usually bent ...
